Back in 2016, the first-ever polymer banknote was issued to replace the paper £5 note, with a cleaner, safer and stronger alternative.

Since then, we’ve seen the introduction of the polymer £10, featuring the portrait of Jane Austen and this year saw the issue of the polymer £20 note, featuring JMW Turner’s portrait.

We’ve seen the £5 and £10 notes prove incredibly popular with collectors, with particular notes selling on eBay for way over face value!

But what makes a banknote collectable? Well… It’s all to do with serial numbers!

We previously listed the serial numbers that you should be looking out for on the Polymer £20 note, from AA01 to AK-47, and unsurprisingly, some are proving more popular than others, but which ones are likely to fetch the most on the secondary market?

Well, we’ve done the hard work for you by taking a look at which polymer £20 note serial numbers are selling for the most on eBay and which ones you should be looking out for.

How much is the polymer £20 worth?

Recurring numbers

If you’ve been lucky enough to find a £20 note with a series of recurring numbers, like the 777777 serial number, you may want to keep hold of it as we’ve seen some which are currently selling on eBay for around £400 – over 20 times its face value!

Similar serial numbers have sold for prices within the same range. The 333333 serial number also sold for £400, so it seems collectors everywhere are desperate to get their hands on a recurring number note!

Another type of serial number you should be keeping an eye out for, is a ‘ladder’. These are serial numbers that have consecutive numbers, like this ‘001122’ note.

One lucky collector got his hands on this note but at a hefty £529…  Other ladder numbers include ‘012345’ and these could currently fetch you a very respectful £350 on the secondary market!

AA numbers

As with previous polymer note issues, the lower serial numbers for the new £20 have proven popular with collectors, with the current average selling price for the AA notes coming in at £40! That’s two times the note’s face value!

At the annual Bank of England charity auction held at Spink and Son Ltd in London the very first polymer note, the £5, with the serial number AA01 000017 auctioned for £4,150! However, this year, the £20 note with serial number AA01 000010 sold for a staggering £7,500, over FOUR times its starting price!

AK47

Considered collectable due to the machine gun connotations, polymer notes with the prefix AK47 were thought to be worth well over face value following the new £5 release in 2016.

A quick look at the most recent eBay sold prices for this serial number, on the new £20 note, show that people are willing to pay £11 over its face value!

What about the £50 note?

We can’t wait to see the new polymer £50 when it’s issued!

So there we have it, the current selling prices for your polymer £20 notes! With less cash being used during the current climate and therefore less notes in circulation, it’s possible this has added to the collectability of these new polymer £20 notes.

The Northern Ireland 2002 Commonwealth Games is the rarest £2 coin currently in circulation – in fact the four designs in the 2002 Commonwealth Games series occupy the top ten list.  There were only 485,500 Northern Ireland 2002 Commonwealth Games £2 coins minted, that’s just 0.1% of all the £2 coins ever struck!

Others to look out for include the 2015 Navy £2 and the 2015 Britannia £2, both coins have recently been issued into circulation and share joint third place on our graph.

Themes have followed a similar pattern over the years with the four constituent countries of the United Kingdom being represented in cycles. The rarest One Pound coin currently in circulation is the Edinburgh £1 which was part of the series depicting the capital cities of the UK.

The Edinburgh design is the only £1 coin with a mintage below 1 million and by way of comparison, over 443 million Royal Arms shield £1 coins were issued in 1983. The 2011 Cardiff £1 and the 2010 London £1 follow closely behind, so all very sought after £1 coins to have.

Another coin to look out for is The Royal Arms £1Although this is a common design which is regularly ignored, make sure to look out for one with a 2008 date – that’s actually the fourth rarest £1 coin.

The rarest coin in circulation, of any denomination, is the Kew Gardens 50p. the Kew Gardens 50p has been valued at up to £50 on online market place eBay. Its status as the most scarce coin has been well publicised, and as a result, many are hoarded by collectors. This chart illustrates just how rare it is compared with other Fifty Pence designs.

The Olympic Fifty Pence series is very popular with Change Checkers, but in terms of rarity, there really isn’t much separating the top 10 designs. The Football ‘Offside Rule’ 50p was certainly one of the most talked about designs, and it also narrowly ranks as the scarcest.

So, keep hold of your coins. You never know what they might be worth in the future! And remember you can Find, Collect and Swap all your coins for FREE with the Change Checker App: www.changechecker.org

The notes have already proved popular with the public, but now they might even be worth a LOT more than £5.

The new £5 notes are printed on Polymer – a thin and flexible plastic material. This means that these new notes are cleaner, safer and stronger than paper notes and feature added security features.
